By reference to Fig. 6 it will beseen that Referring to the drawings, the burner the construction thereshown of the member 85 shown in4 Fig. l is of the usual ring type in 7is in certain respectssimilar to that conkwhich there is the ring bodyportion 1 with struction which has been previously dei a neck 2 and themixing end 3, all of which scribed. The top surface, however, is fiatare hollow, and the mixing end 3 has a cenand is provided with theopening 7b.` There tral spider 4 with an opening through which istheinner chamber 7 c and the openingin 0n the gas supply pipe with itsproper orifice the rear wall of the chamber which is indimay beextended.

These openings whichextend at the center thanY they are toward the outer through the topsurface receive the full prescircumference. i p sure of the gas, (and itfrequently happens There is an inner chamber 7h and there is that due tothe 'pressure the gas blows itself an opening 7 in the rear wall whichis of out, or inother words, the flame-is blown less diameter than thegreatest diameter of 105 away from the top of the burner b'ecause of thechamber 7h.'

It is difficult to This form of insert has beenfound very control these matters. except by the use of effective, infact, in many respects it gives some special re ulating mechanism whichbetter results than the other forms 4of in` is too expensive orinstallation in homes for serts in that it seems to provide a'greater11.0

mixed, and this mixture passes `The burner structure in which the insertis inserted is indicated at 7L and has a recess 7m which at the lowerpart thereof is provided with an inwardly extending flange 7 which hasan opening 7o which is of less diameter than the diameter of the opening7 The inner peripheral -edge of the insert rests upon the inwardlyextendingflange 7,

and as will be noted, this flange A7n extendsbeyond the inner' wallofthechamber 7k.

It will be seen that'in this ystructure the use of the flange 7 tureproper,

in the burner structhe same eii'ect, sofar as the chamber isconcerned,'is'obtained with respect tothe showing in Fig 8 asis obtainedpinge upon the iiange 18 and be deflected so;

with respect to the showing in Fig. 7

The insert members as before `stated are inserted in the openings whichare formed in the-ring portion 1. and the gas whensupplied to the burnerpassesthrmgh the openings 9 in the inserts.

4Itis well a this character known fact that in burners of the gas in theburning receives what is known as primary air and second ary air, thatis to say, at the mixer-there is a certainmmouirit of gas and air which`are burner and through the orifices of the burner, but when the gas andair.- mixture -before described is burning there is a certain amount ofair which is takenv up from I less diameter than the amosphere at thetime of burning. The.

present burner is no dierent in this respect 'than those which have beenheretofore used. However, due tov the fact that the insert member 7 ishollow, and further, due to the fact that what may be termed the inletopening vin the rear wall of the insert is of the chamber of the insertitself, thegas which enters the chamber of the insert is defiect/ed andits pressure somewhat reduced so hat the openings in the top near theedge of the insert, are relieved-from the high pressure,

and therefore when the .mixture of primary air and gas are ignited afterpassing` through the insert members, the auxiliary air which is suckedin to comlete the combustion, does not cause any lowing out due to thefact that the pressure of the gas which row of openings is diminished.-Y

It should be noted that the insert' members may be made having obtainedwhere the vinof depressions '16 in through -the surface of the insert,which openings areV passes throughthe outside of any desired material,good f it was made of lava.

In Figs. 3 and 4 there is shown different form of burner larly intendedfor use in a vertical position. The burner'consists of a head portion'13with a neck portion 14 of increasing diameter, and at one end is 'themixer portion A15. The head member 13 is provided with a plurality thesame manner as has before been described, and inieach'of these as theinsert-7 which functions inprecisely the same way.. In vertical burnersof this kind the condensation which may'drip from the coils of a waterheater or any part of an apparatus in which such 'a slightly' ,which isparticudepressions there is insertedI an insert such burners are used isliable to contact with the inserts and cause the fiame -to beextinguished. In order to protect these inserts the head portion-13 isprovidedwith anextending flange 18"V which extends slightly beyond theinserts so .that

the outer end of the flange is substantially in line with the lowerportion of each insert 'so that condensation which may drip will imthatit-ywil1 not come iir contactwith Athe 'i I burner openings proper.Having described my invention, -I-claim 1.
